All uniforms for these games will feature “IX” in the front of the jerseys while player names and uniform numbers will remain the same on the back of the jerseys. In addition, commemorative adidas WNBA Title IX shirts will be available for purchase at WNBAStore.com.

“As the most successful women’s sports league in the world, we truly believe the WNBA is a proof point of the impact of Title IX,” said WNBA President Laurel J. Richie. “The women of the WNBA – and all of the men who enjoy the game or have daughters and sisters who dream of becoming professional athletes – are beneficiaries of this legislation. We are proud to recognize this important anniversary.”
